ranged to be operated electrically, the object of the invention being toproduce a multiple tracker board mechanism for the purpose wherein onemechanism may be thrown into or out of action, and anothersimultaneously likewise thrown out of or into action and means wherebythe one mechanism may be independently operated to position the musicsheets thereon while the other mechanism is in operation. The demand forthis type of v proved 1I1V81'll31011 consists primarily of a mechanismhas been greatly increased by the present popular use of automaticmusical instruments in connection with moving picture theaters and othershowhouses where it is desired to play different pieces of music tofitthe different scenes being enactedon the electrically operated andcontrolled musical instrument canbe readily adapted for this purpose. p

While the invention, as at present advised, is especially adapted foruse in connection with pipe organs, still in practice it could as wellbe adapted for use in other connections; For the purpose of the presentillustration however, we will consider the same as used in place of orin connection with the keyboard used in connection with pipe organs foroperating the various valves and stops, the present invention especiallyrelating to their operation by electrically controlled means. a

A further object of the invention is to produce a simple and inexpensivedevice and yet one which will be exceedingly effective for the purposesfor which it is designed.

These objects I accomplish by means of.

such structure and relative arrangement of the parts as will fullyappear by a perusal 5 of the following'specification and claims.

-Referring now more particularly to the characters of reference on thedrawings, I will let the numeral 1 designate the key board and thenumeral 2 any suitable frame- .work for supporting my improvedmechanism.

For thepurposeocf the present illustration I have showna double trackerboard mechanism in which the numeral 3 designates the music sheetcarrying roll of one mechanism and the numeral 4 designates the take upparts in the roll of the same mechanism while the numeral designates thecarrying roll of the other mechanism and the numeralfi the take up rollthereof.

means at their ends for projecting through the perforations in such amanner as to avoid.

any possibility of catching and tearing the sheet 9 when passing into orout of a perforation. 1

Between the rollers 5 and 6 are members 16, 17, 1s, 19, 2o, 21, 22, 23,and 24 of similar structure to the members 7 to respectively.

- My improved invention" embodies especially the following features,namely:

A forward operating mechanism for the music sheets wherein one sheet isoperated forward for playing the musical instrument 7 wh1le the otherone 1s 1n lnoperative position; a means for rewinding the inoperativewhile the other one is in inoperative position, is

the numeral 25 designates the shaft for oper ating the roller 4 and thenumeral 26 the shaft for operating the roller 6. On the shafts 25 and 26are gears 27 and 28 respectively meshing with pinions 29 and 30 mountedon shafts 31 and 32, this latter mechanism being for the purpose ofreducing the speed.

Keyed to -the shaft 31 are two sprocket wheels 33 and 34, the sprocketwheel '33 being of a larger size than the sprocket wheel 34,

and similarly, on the shaft 32 are sprocket 5 wheels 35 and 36. Thesprocket wheel 34 is connected by a chain37 with the sprocket wheel 38turnable on the shaft 39 driven b the driving motor 40, such sprocket38,

having a clutch face 41. A chain 42 connects the sprocket 34 with thesprocket 43 turnable on the shaft 39v and having a clutch face 44, allfor a purpose as will appear. The numerals 45, 46, 47, 48, 49 and 50indicate parts on the other mechanism similar to the parts 37, 38, 41,42, 43 and 44 V The numeral 51 designates a selecting lever mounted at apoint adjacent the keyboard 1 and arranged to throw either the roller 4.

or 6 into operative position to advance the corresponding music sheetand to simultaneously discontinue the operation of the other roller andits music sheet. plishcd by means of the following structure, namelyz."I

A link 52 connects the lever 51 with the bell crank 53 which bell crankis connected at itsend by a link '54 with bell crank 55.

Such bell crank 55 connects at its other end with a push rod 56 commonto two levers 57 and 58. The lever 57 is connected with a collar 59slidably keyed to the shaft 39 and having a clutch 60 arranged toengageth'e" clutch face 41. The lever 58 is connected with a collar 61'keyed to the shaft '39 {and provided with a clutch 62- arranged forengagement with the clutch face 47.

' sprocket 33 and the shaft 31.

This is accom- Assuming that the roller 4 is to be thrown intooperation'to draw the music sheet off the roller 3 and over the roller 7the lever 51 would then be moved to the left, which through the mediumof the link mechanism described will push the push rod 56 to the leftand operate' the lever 57 so as to move the clutch 60into engagementwith the clutch face 41 on the sprocket wheel 38. With this operationthe push rod-56 will pull'on the lever 58 so as to move it to thatposition in which the clutch 62 will be entirely free from anypossibility of engagement with the clutch face 47 on the sprocket 46.When the clutch 60 is engaged with the face 41, the shaft 39 beingrotated by the motor 40, this will rotate the sleeve 59, sprocket 38,and through the medium of the chain 37, will rotate the pinion 29 willdrive the gear 27, shaft 25 and roller 4 to advance the music sheet 9.

When the music sheet 9'is being advanced over the roller 7 by. means ofthe operation just described it becomes necessary with suchadvancementto make electrical connections between the roller 7 and thefingers 15, so that as the fingers 15 contact with the roller 7 throughthe perforations in the sheet 9, suit-' Thus the able mechanism may bethrown into opera- 1 tion to playthe musical instrument, and this isaccomplished as follows:

lV hen the lever 57 is thrown over to engage the clutch 50 with theclutch face 41 a contact point 63 on the said lever 57 is moved intoengagement with the switch blade 13 whereupon a circuit can be completedas follows: A wire 64 connects the point 63 with aeource of electricalenergy 65 which may be of any desired or adaptable kind.

Another wire 66 leads from the source 65 to an electro magnet 67 fromwhich another wire 68 leads toone of the fingers 15. The lingers15 ofcourse are insulated from the beam 14.

The electromagnet 67beingthus energized by the closing of the circuitattracts the point 69 on the operatingmechanism 70 of the musicalinstrument. No connection is shown between the member 7 O and the valvesand stops of the musical instrument since this structure is common. Itis of course understood that there is a separate circuit for each one ofthe fingers 15, each energizing a similar electroma-gnet which inturnattracts a member of the the same construc tion the member 70, suchmembers 70'be' ing operatively connected to actuate the pipes of theorgan in any manner common to the art; a

hen it isdesired to cease taking up the sheet 9' on the roller 4 and totake up the sheet 18 on the roller 6,the lever 51 is moved to the right.This acts on the lever '57 to throw the clutch 60 out of'engagement withthe clutch face 41 and also'breaks thecontact between the points 63 and13. At the same time the lever 58 is actuated to move the clutch 62 intoengagement? with the clutch face 47 and the points 72 and 22 intocontact with each other. This, through the mechanism which correspondsto that mechanism described for throwing. the roller 4 into action,throws the roller 6 into action and advances the sheet 18. The fingers24 then act the sameas described for the fingers 15 to completethe'following circuit, namely: n

From the source of electrical energy. 65 through the wire 66,electromagnet 67 wire 68, wire 68 to one of the'fingers 24 thencethrough the roller 16, arm'17, point 20, wire 21, point 22, point 72,and wire 73 back to the source 65 thus throwing the electro-' magnet 67into action and causing it to operate the members 69 and 70 as in amanner previously described. j V By moving the lever 51 to verticalposition the levers 57 and 58 will be so posiv tionedthat none of themechanism'for op erating the musical instrument will be in drivingrelation with the shaft 39.

WVhen the roller 4is in operation and the roller 6 is not in operationfor advancing the sheet 9 to operate the musical instru-' ment, or viceversa 01' when neither of said rollers is being so operated, and it isdesired to reposition the sheet 9 or the sheet 18 on the rollers 4 or 6without rendering any music therefrom but merely for the purpose ofbringing another selection into position ready to be played, this isacomplished by means of the following structure, namely:

The numeral 74 designates a small lever positioned adjacent the keyboard1 and connected by a link 75 with a bell crank 76 which in turn isconnected at its other end by a link 77 with another, bell crank 78.This latter bell crank 78 is pivoted to a push rod 79. On one end of thepush rod 79 is pivoted a lever 80 connected with a sleeve 81 slidablykeyed to the shatt 39 and having a clutch 82 arranged to engage theclutch face 44 of the sprocket wheel 43. On the other end of the pushrod 79 is connected a lever 83, which lever is connected with a sleeve84 slidably keyed on the other side of the shaft 39 and providedwith aclutch 85 arranged to engage the clutch face 50 on the sprocket 49. Bythrowing the lever 74 to the left, this, through the medium of the linkmechanism shown, will move the push rod 79 to the right and thus actuatethe lever 80 to move the clutch 82 into engagement with the clutch face84 which will place the sprocket wheel 43 into driving relation with theshaft 39. This, through the medium of the chain 42 and sprocket wheel34, will drive the shaft 31, pinion 29, gear 27 shaft 25 and roller 4 soas to rotate such roller 4 in its forward direction. Due to playingpurposes only.

the relative size of, the sprockets 43 and 34 the roller 4 will berapidly turned which will quickly move the sheet 9 over the roller 4 toany desired positionand-this canbe accomplished while the roller 6 isbeing operated: to actuate, the musical instrument.

:VVh'enthe clutch 82 is engaged with the clutch face 44 the clutch 85 issimultaneously moved so as to be out of any possible engagementxwiththeclutch face 50 so as not to affeet the opposite mechanism, but whenthe roller 4 is being operated for playing the musicalinstrumenttheroller 6 can likewise be moved to position the sheet 18thereon merely by moving the lever 74 to the right; or by having thelever 74 in vertical position neither of the clutches will be inengagement with'its corresponding clutch face so asto allow of theoperation of the mechanism for V7 hen it is desired to rewind thesheets- 9 or 18 on their rollers 3 and 5 when the cor- V respondingrollers 4 or 6 are not in action this can be accomplished by means ofthe following structure viz: A lever 86 is fulcrumed adjacentthekeyboard 1 and is connected by a link 87 with a bell crank 88, theother end of said bell crank being connected by a link 89 with a bellcrank 90, which bell crank 90 is connected with a push rod 91 connectedat its ends with levers 92 and 93 respectively. The lever 92 isconnected with a sleeve 94 slidably keyed on a shaft 95 and providedwith a clutch 96, while the lever 93 is connected with a similar sleeve97 slidably keyed on the shaft 95 andprovided with a clutch 98. Securedon the shaft 95 is a sprocket wheel 99 connected by a chain 100 with asprocket wheel 101 keyed to the shaft 39 whereby theshaft 95 rotateswith the shaft 39. On the shaft 95 adjacent the sleeve 94 is a sprocketwheel 102 having a clutch face 103 which sprocket wheel 102 is connectedby a chain 104 with a sprocket wheel 105 keyed to a shaft 106 whichcarries the roller 3. Similarly keyed to the shaft 95 adjacent thesleeve 97 is a sprocket wheel 107 having a clutch face 108, suchsprocket wheel 107 being connected by a chain 109 with a sprocket wheel110 keyed to a shaft 111 which carries the roller 5. v

If it is desired to rewind the sheet 9 the lever 86 is moved to the leftwhich, through the medium of the link mechanism described moves the pushrod 91 to the right and throws the lever 92 so that the clutch 96engages the clutch face 103 and operates the sprocket wheel 102, which,through the medium of the chain 104 advances the sprocket wheel 105 andthe shaft 106 to wind the sheet 9 upon the roller 3. With the reverseaction the clutch 98 is thrown into engagement with the clutch face 108and operates the sprocket wheel 107 which,through the medium of thechain 109 operates the sprocket wheel 1 10 to operate the shaft 111 toWind the sheet 18upon the roller 5;

The motor 40 is driven by a suitable connection with the source ofelectricity 65 and the time in which the music is played is controlledby regulating the speed of the motor with a resistance lever 112 whichcon trols a suitable resistance 113 of any desired type. i v i 3 L While-this specification sets forth in detail thefpresent and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted-to as do not form a departure from the spirit ofthe invention as defined by the appended claims.
